In a South Asia that was becoming more and more polarised, radio played a significant role for more than 50 years, providing everything from World War II news to the broadcasting of music from hit movies. Examining Hindi-Urdu radio throughout its heyday from the 1930s to the 1980s, Radio for the Millions demonstrates how it fostered global communities of listeners. According to Isabel Huacuja Alonso, despite attempts by politicians in Britain, India, and Pakistan to appropriate the medium for political ends, radio mostly eluded their control. She shows how the medium allowed listeners and broadcasters to oppose the political, cultural, and linguistic goals of the British colonial administration and the independent governments of India and Pakistan that followed. Rather than being merely a tool of nation building in South Asia, radio created affective links that defied state agendas, policies, and borders. It forged an enduring transnational soundscape, even after the 1947 Partition had made a united India a political impossibility. Huacuja Alonso traces how people engaged with radio across news, music, and drama broadcasts, arguing for a more expansive definition of what it means to listen. She develops the concept of ?radio resonance? to understand how radio relied on circuits of oral communication such as rumor and gossip and to account for the affective bonds this ?talk? created. By analyzing Hindi film-song radio programs, she demonstrates how radio spurred new ways of listening to cinema. Drawing on a rich collection of sources, including newly recovered recordings, listeners? letters to radio stations, original interviews with broadcasters, and archival documents from across three continents, Radio for the Millions rethinks assumptions about how the medium connects with audiences.
